PyPy support breaking CPython compatibility?

Please take a look at the changesets:

https://bitbucket.org/tkadm30/libschevo/commits/745d1aeab5c6ee0d336790cf13d16f327e10c2f8
https://bitbucket.org/tkadm30/libdurus/commits/875636e9b6caa840fd50ca87d69217d87fc06f43

In short, it seems PyPy automagically adds a __weakref__ attribute to 
__slots__, causing the CPython interpreter to raise a TypeError...


Cheers,

Etienne
